On reactions of thiadiazinones: synthesis of new 6-arylidene-1,3,4-thiadiazin-5-ones
摘要:
6-Benzylidene-, 6-(furan-2-ylmethylene)-, and 6-(thiophen-2-ylmethylene)-1,3,4-thia- diazin-5-ones have been synthesized by condensation of 1,3,4-thiadiazin-5-ones with appropriate aromatic aldehydes.

- k) were synthesized from the reaction of the corresponding hydrazonoyl halides 1 with ethyl mercaptoacetate (3). These compounds underwent intramolecular cyclization to 1,3,4-thiadiazin-5-one derivatives (5a - k) in the presence of MeONa or LiH. The structures of the synthesized compounds were confirmed by their elemental analyses and spectral data.
